Aquifers are the underground reservoirs that supply our wells and act as the "water bank" for future water needs. .
Derricks exist so that the pipe needed to drill deep into the earth can be raised to an upright position.
- Water consumption by drilling companies is enormous. The work of the drill bit must be aided by large infusions of liquids.
- The chemicals used in drilling are mostly toxic, so petroleum companies and the public try to balance the need to drill with the need to keep water supplies safe for now and for the future.
